Ion-Induced X-Rays from Gas Collisions

Abstract

With the increasing availability of low energy ion accelerators, sophisticated nuclear instrumentation and detection systems has come a serious interest in using x rays to study the basic physics of ion-atom collision processes. A many-electron ion colliding with an atom can produce a large number of atomic states, singly and multiply excited, that are not seen when the atoms are excited by photons or electrons. Spectroscopic and lifetime measurements on these states are of fundamental interest. A very effective way to make such studies is by looking at single collisions of ions with atoms or molecules in a gas. Single-collision excitation of x rays by heavy ions is also important because of its applications in such diverse fields as atmospheric physics, controlled thermonuclear fusion, nuclear physics, chemistry, solid-state physics, and materials research. It is known that x ray yields resulting from inner-shell vacancy production in solid targets depend, in some cases, on the configuration of the outer-shell electrons.
